I don't get why people insist on looking at guitars as investments, unless we're talking either iconic vintage instruments or boutique stuff from a handful of elite luthiers. To me, it doesn't seem realistic to be concerned about how a Bourgeois/Eastman collaboration will impact the resale value of your Bourgeois guitar. I respect Dana Bourgeois' guitars-- the ones I've played (and an OM I owned briefly) were well made and good sounding. I've liked the Eastmans I've played, and consider them among the best of the Chinese import copies of American designs. It should be interesting to see what comes of this collaboration.
